iMPRovEMENT IN uTiLlzlNG sEwERA'GE MATTERS.

The Schedule referred to Ln these Letters Patent and making part of the same.

- To all whom it mail concer-n Beit known that I, J. BURRows HYDE, of the city, county, and State of New York, have invented a new and useful Method for Utilizing and Deodorizing Sewerage and Privy Deposits, Urinal, and the Otfal of cities and towns; and I do hereby declare the followiuglto be a fulland exact description thereof, reference being had to the accompanying'drawings and the letters of reference thereonryj v'lhe nature of myinveution consists- First, in constructing a chamber, pocket, or trap, in the sewer-conduit a at any convenient point, as at c, by depressing its lower surface or bottom to any proper depth; and also, when necessary to do so, by increasing its width' beyond the sides of the sewer, the location of the trap being at any proper place for the most eectual gathering of the material. The shape of the chamber may be varied, but I prefer to construct it so as to be deepest at its forward end, as atb, with a gradual ascent from that point tothe bottom of thesewer, or curved, as shown in the drawing.

If the chamber be differently shaped it should, in all cases, be deepest at some partby depressing the bottom vat that place, for obvious reason.

VOu this depressed or deepest part of the chamber I construct 'a vertical shaft, d, of proper diameter, from the chamber to the surface of the ground or roadway, where the opening should be closed by a proper cover, as at c, which should be easily secured or removable.

In this condition the solid matters that flow along the sewer will sink into vand, settle in this depressed chamber, while the fluids will pass on to the outlet ofthe sewer. And, in cases where convenient and uecessary, I provide a grating, t, of thin strips of wood placed vertically and edgewise to the current, with pro` per intervals between them, to arrest the Heating matters that may pass wherethe chamber is overow- `ing with water.

This grating should cover about half the outlet elidof the sewer, and be hinged at the bottom, and should be provided with a counterbalauce, o, to drop the. grating inward to the chamber, and clear the interstices of any substance that may collect there and obstruct the water How.

f The grating being held in its proper vertical position byv a chain, la, having its upper end secured near the top of the vertical shaft tov facilitate lowering and lifting and securing the grate. l By this system the more solid matters are 'not only pocketed and retained from being washedout at the mouth of the sewer, to settle and dcompose, vevolving most oifensive gases, but are saved in a condition for easy removal through the shaft d, placed in carts, and treated for fertilizing purposes.

Second, for the more perfectly ei'ecting the desired objects, it is best that this fetid matter should be deodorized, to prevent, as far -as possible, the escape of noxious gases from the sewer-pocket, and

also when it is being transported iu carts, and this I effect as follows i I prepare ulmine, the fine pulpy portion ofpeaty4 matter, by drying and grinding it to powder.

This material I place in the empty chamber to a depth of twelve inches,"more or less.

The sewerage matter will readily combine with this ulmine, which is not only a prompt disinfectant, but holdsthe sulphuretted hydrogen and amm'oniacal gases on -which it seizes in large volume,

and it will not part with them until itselt' is deconi posed. If at any time onopening the trap disagreeable odors shall be evolved from the chamber, a few inches depthnc'f the powder should be thrown over the surface, and when the material is removed from' the chamber and placed'iu carts for transportation', the surface'gmay be in like manner covered with the ulmine,v which will arrest all offensive odors from eseapiugwheh passing along the street.

This dry ulmin'e powder has the property to yalso utilize the salts and gases of nrinal fluid.

It will arrest the escape of ammonia and prevent the urine from decomposing and besides is biglily valuable in public urinals, by placipg it as described, first, iu the empty vessel, and adding afterward, if necessary, as before described.

`It Will also serve a similar purposein privy-vaults upon fecal mattei', besides, preventing it from waste anddecomposition, while, at the same time, in all of the desflribed uses or applications its addition not only increases the bulk ofthe mass, but itsel falso contributes anessential element of fertilization, which iti-adds to the other materials for vegetable nourishment.

It also, in all the cases described, furnishes highly l useful sanitary benefits, particularly in a crowded population.

' When there is an accumulation'of Huid in urinals, a weak solution of sulphuric acid in water may be sprinkled over the surface before covering it with the nl mine powder. A

Itwill `partially arrest the decomposition of and to a. great degree, if not'eutirely, prevent the lescape of unhealthy odors from the oifal of slaughter-houses, fish, and other markets, and the carcases of dead animals, if it be admixed with or they be well covered by the described material.

What I claim and desire to secure'by Letters Patent s 1. The construction and use of a sewer-chamber or trap, inthe manner and for the purpose described.

2. The use of the described material, iu the manner and for the purpose Vset forth.

J. BURROWS HYDE.
